Feasibility of Timesaving When Using Histolog Confocal Laser Endomicroscopy for Margin Assessment in Prostatectomy Specimen

NCT ID: NCT07141121Sponsor: Icahn School of Medicine at Mount SinaiLast updated: 2025-10-07

Summary

This study investigates a new, faster way to find cancer cells on the surface of the prostate during radical prostatectomy surgery. A recently FDA-approved device, called the Histolog Scanner, gives high-resolution imaging of the surface of fresh tissue using ultra-fast confocal microscopy, which allows physicians to make surgical decisions quickly.

Detailed description

The goal of this time saving feasibility study is to gain early insights into whether Histolog Scanner can maintain the integrity and safety of NeuroSafe margin assessment while alleviating the heavy time burden of NeuroSafe in the US setting before starting a larger clinical trial. This way, patients can be offered optimal nerve sparing without adding to the administrative burden and cost associated with NeuroSafe. What is new about the study is that the researchers intend to do a cost and time economics analysis using United States market prices that will inform discussions in the future about the utility of this device in the United States.

Arms & interventions

  • DeviceHistolog Scan

    Upon prostate removal, the prostate is taken to the Histolog scanner, dipped in proprietary fluorescent dye, rinsed with saline, and then scanned on five different sides. This involves simply placing the prostate on the surface of the scanner and acquiring images on each side, giving a high-resolution (cellular level) microscopic imaging of the prostate's surfaces. Once images are collected, the prostate is returned to the pathology lab to undergo the NeuroSafe procedure, which is standard of care (SOC).

Outcome measures

Primary

  • Proportion of Surgeries with Histolog Scanner Attributable Time-Saving Greater Than 20 Minutes

    Defined as a positive difference of time taken using NeuroSafe technique vs time taken by Histolog scanner in margin assessment.

    Time frame: Immediately after procedure

Secondary

  • Agreement Between Histolog and Final Histopathology Assessment

    Time frame: Immediately after procedure

  • System Usability Scale (SUS)

    Time frame: "Baseline" or "Day 1" and through study completion, an average of 1 year

  • Pathologist Usability Scale (PUS) score

    Time frame: "Baseline" or "Day 1" and through study completion, an average of 1 year

  • Count and percentage of specimens where the Histolog Dip impacted the ability to make final margin assessments in pathology

    Time frame: Immediately after procedure
